- Introduction to GGC - Interconnect Help
Introduction to GGC Google Global Cache (GGC) allows ISPs to serve certain Google content from within their own networks This eases congestion within your network, and reduces the amount on traffic on your peering and transit links If you do not currently host a GGC node, but would like to enquire about availability, please use this web form
- Network Changes - Interconnect Help
We make use of either static routes or Router Advertisements to configure the default IPv6 gateway on the GGC machines: If you prefer we use a separate gateway as advertised via Router Advertisements, ensure these are enabled and working properly
- GGC Batch Repairs - Interconnect Help - Google Help
GGC Batch Repairs is a system for ISP Partners to self-manage selected repairs for the GGC nodes they host The differences between the way GGC repairs have traditionally been managed, and the self-management enabled by GGC Batch Repairs are described below
- Carrier Grade NAT - Interconnect Help
Carrier Grade NAT Introduction This document describes how to configure Google Global Cache (GGC) nodes to operate with your Carrier Grade NAT (CGN) systems Once configured, this allows traffic between the GGC node and private user IPs to bypass the CGN GGC has no requirement that "private IP space" be in the RFC1918 allocation
- Configuring BGP - Interconnect Help
The GGC BGP-session is not intended to be permanently "up" and should not be monitored A maximum of two BGP sessions with AS11344 are permitted at a single GGC node; one for IPv4 and one for IPv6 Consider using a route server if you need to advertise aggregated prefix data from multiple sources on your network
- BGP Community Support for Google Serving - Interconnect Help
BGP Community Support for Google Serving Background Google supports the exchange of BGP community tags with GGC nodes and peering sessions to signal important properties of a prefix for reporting, load-balancing, or policy enforcement All information exchanged should be considered advisory
- Preparing USB Install Media - Interconnect Help
The GGC server installation image can be re-used for multiple installations The image for GGC routers is provided by GGC Support and is tailor-made for each specific device
- Current Traffic - Interconnect Help
GGC egress-ingress ratio Egress-to-ingress ratio measures the ratio between the asset egress and the cache fill for a single GGC serving point A simple interpretation of this value is that the node is serving X many times the amount it is downloading at this point in time" where X is the value observed on the graph
